AQUILA GNSS Helical Antenna Enhances Precision
The AQUILA SZA-N-5G49 active helical antenna from Synzen Precision Technology delivers compact, multi-band GNSS performance for reliable positioning in IoT, agriculture, and autonomous systems. Supporting GPS, GLONASS, BDS, and Galileo across key frequency bands, it ensures stable signal acquisition in varied environments. As a distributor of RF and connectivity solutions, SE Spezial-Electronic GmbH provides integration expertise to optimize these components in industrial deployments.
Key Features and Design
The AQUILA features a right-hand circularly polarized (RHCP) helical structure for stable phase center and low axial ratio (≤1.5 dB), ideal for RTK applications. At 55.6 x 27.5 mm and under 32 g, its size suits UAVs and portable survey tools. An integrated low-noise amplifier (LNA) offers 33 dB gain, boosting sensitivity for faster acquisition, with an SMA male connector for easy setup.Encased in a durable ABS plus PC radome with IP67 rating, it withstands outdoor rigors. Operating on 3-15 V DC with 20 mA typical consumption, it fits battery-powered designs. RHCP polarization minimizes multipath errors in urban or obstructed settings, while out-of-band rejection (>35-40 dB) reduces interference.
Technical Specifications
The AQUILA's specs support wideband GNSS, including L1/L2/L5, E1/E5/E6, and B1/B2/B3. Key parameters are summarized below.|

Applications and Compatibility
In precision agriculture, the AQUILA supports sub-inch guidance for drones and tractors via accurate mapping. Survey tools benefit from multi-constellation tracking for remote data collection, while industrial timing uses its low phase noise for network synchronization.For UAVs, robotics, and autonomous platforms, the compact form enables real-time navigation. Asset tracking leverages IP67 durability for telematics in logistics.
The AQUILA integrates seamlessly with u-blox GNSS receivers, enhancing system performance. It pairs effectively with the ZED-F20P triple-band module, covering L1/L2/L5 for resilient positioning in robotics and agriculture. For global decimeter accuracy, it supports the ZED-X20P all-band receiver, including L6 for Galileo High Accuracy Service (HAS) via PPP-RTK, without needing base stations. This compatibility extends to SBAS, QZSS, and NavIC, broadening deployment options.
Benefits for System Designers
Designers appreciate the 33 dB LNA gain and ≤2.0 dB noise figure for quick locks in dynamic scenarios. Stable performance across bands ensures RHCP purity, lowering error rates versus competitors. RoHS compliance and -45°C to +85°C range ease certifications for automotive and aerospace.As GNSS evolves with 5G IoT, the AQUILA enables future-ready designs.
